Description

Intracellular dye injections of protoplasmic astrocytes from the CA1 region of hippocampus of 3 week old rat reveals highly ramified spongiform processes that span territories with minimal overlap. Astrocytes were filled with Alexa 488 (green) and Alexa 568 (red). Optical sections were generated with a single photon confocal microscope and are presented here as a maximum projection image. This image has been downsampled from the raw data image which can be accessed using the link provided to the Cell Centered Database.

Technical Details

Male Sprague Dawley rats were anesthetized and perfused transcardially with with Ringer’s solution (37°C), followed by 4% paraformaldehyde (PFA) in PBS (37°C, pH 7.4). Tissue was sectioned (100 µm thick) using a vibratome, and injected with a BX50WI microscope (Olympus, Melville, NY) and, using infrared differential interference contrast videomicroscopy,cells with a small diameter soma (approx. 7–11µm) in the stratum radiatum of CA1 were located and impaled with glass micropipettes filled with either AlexaFluor 488, 20mM AlexaFluor 568 in 200mM KCl. The astrocytes were filled using a 0.5 Hz pulses of current until all of the processes were brightly fluorescent. After several astrocytes were filled, a slice was placed in the 4% PFA overnight at 4°C. Slices were then imaged after coverslipping in Gelvatol. Confocal images were acquired with a BioRad Radiance2000(Hercules, CA) attached to a Nikon E600FN (Kanagawa, Japan) microscope equipped with a Nikon (Tokyo, Japan) 60× oil objective (NA 1.4).
